2011 Shelby GT500 ETC Boost limiter?

I've run into a brick wall with a limiter on a 2011 GT500.. Seems that no matter what table I increase for commanded torque or do a complete disable of all torque calculations, the ETC still closes. Although not as rapidly with the complete torque disable, but still going down to 70% at redline.

There is a good 40-50whp still to be made if this can be deleted. The 2011 doesn't have the same tables as the 2012/2013 Shelbys.

Maybe something to look into? Or is there something I'm missing?

Does it happen on the street, or only on the dyno?

only managed to tune it on the dyno.. never datalogged it on the streets..

my dyno is a loaded dyno, so should be the same as the street..

See if it happens on the street. Front tires aren't spinning on the dyno

still have a closing etc even on the road.. disabled all torque management to the extent the throttle lags after a WOT run..

Stock or aftermarket TB?

post file, did you modify DRIVER DEMAND what is your pedal START & END set to?

eric, seems to be a load limiter..

Im reading airload maxing and staying stable at 1.57.. Etc goes down to 75% then to 45%... Like how u explained in the 2013/2014 GT500 stuff, no matter what power is always in 10hp of each other.

All limiters I've maxed out to 2.0 and I've disabled all torque tabs and tables.

Can you look into it please?

Eric, any updates?

Email support and I will look into it.

sent! thanks

hey
How did u solve the issue !!! i have the same thing with shelby 2011
1. speed limit is never changing
2. no matter what adjustments i do for the AFR it stays the same!!

thanks

whats your AFR, any parts

Seems I've hit another limiter. The customer has added a crank pulley and we're getting around 19lbs of boost out of the blower. End of the run the throttle body is closing down to 91% then to 85%.

With just the upper I had increased the load limiters as Eric suggested, but now all limiters have been maxed out.

Would Pedal POS WOT end have anything to do with this?

Looking over the file, ETC Torque management seems to come into play.

There are 2 tabs:
- Scheduled Torque Max (Set to stock values - I will increase and try this out)
- Torque Max (Which I had previously maxed out.)

If anyone else has any other ideas, please put some input in. With regard to the 2013/2014 GT500s, there seems to be a limiter which is: Load Limit vs RPM vs ECT.

I normally see loads of 1.85 but once I hit that, load decreases an the throttle seems to close?

Is this something HP Tuners needs to add for the 2010/2011 GT500s? Or would it be something completely different?

what do you have your start and end WOT?

Factory settings

Are the torque and torque inverse tables accurate?

Isnt it driver demand table limiting it?
